When the wire number tube 6 passes the position of the printing mechanism 5, the printing mechanism 5 prints the wire number tube 6 in the tube placement slot 11. The present invention provides an open tube placement slot 11 on the bottom shell 1, which can solve the problem that the traditional wire number machine cannot insert the tube into the print head for printing or the tube is blocked due to the inadequate insertion or the excessive length of the tube insertion.
